The name "white blood cell" derives from the physical appearance of a blood sample after centrifugation.White cells are found in the buffy coat, a thin, typically white layer of nucleated cells between the sedimented red blood cells and the blood plasma.
Plant oils or vegetable oils are oils derived from plant sources, as opposed to animal fats or petroleum.There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil:
The white blood cell differential is a common blood test that is often ordered alongside a complete blood count.The test may be performed as part of a routine medical examination; to investigate certain symptoms, particularly those suggestive of infection or hematological disorders; [5] [6] or to monitor existing conditions, such as blood disorders and inflammatory diseases.
Castor oil is a vegetable oil pressed from castor beans, the seeds of the plant Ricinus communis. [1] The seeds are 40 to 60 percent oil. [2] It is a colourless or pale yellow liquid with a distinct taste and odor.
In 1993, the American Petroleum Institute (API), categorized base oils into five main groups. Chemical and physical characteristics are defined for Groups I through III that reflect how refined they are, correlating in some way to high and low-temperature viscosity, oxidative stability, volatility, and so on.
Sharks typically targeted for their liver oil include the school and gulper shark, and the basking shark (pictured). [1] All three of these species are either endangered [2] [3] or critically endangered [4] due to overfishing according to the IUCN, although a legal targeted fishery for basking sharks no longer exists.
Cajuput essential oil in clear glass vial. Cajuput oil (also spelled cajeput) is a volatile oil obtained by distillation from the leaves of the myrtaceous trees Melaleuca leucadendra, Melaleuca cajuputi, and probably other Melaleuca species.
Pine oil is a higher boiling fraction from turpentine.Both synthetic and natural pine oil consists mainly of α-terpineol, a C10 alcohol (b.p. 214–217 °C). [5] [1] Other components include dipentene and pinene. [6]
